    • Abstract
  • The Plaxis 2D finite element software is used to analyze the deformation laws of a new pile-soil-support system with HS model based on a foundation pit in Shanghai. Contrastive analysis is conducted between finite element and measured values. The results show that the Plaxis 2D can predict the deformation of the new pile-soil-support system. The existence of tube-inclined brace changes the deformation laws of the traditional double-row piles and can reduce the displacement of top of the double-row piles effectively. The deformation of retaining piles of the new pile-soil-support system satisfies the safety and deformation requirements of the foundation pit. The new support system has no inner supports, and it avoids a lot of construction waste generated by the construction and demolition of temporary supports. It is safe, economic and green environmental protection, and it can provide reference for deep and large foundation pits in soft land areas.
